Headlight gives cool light (cold temperature, maybe about ~5000 K), 5 modes but i prefer continuous light - there's low mode, middle and high. Low looks really torelable and probably I'll be using it 99% of time. Especially in city it's sifficient but even inside some forest or something like that low or middle will be ok. Production quality looks good too, a handle also. There's a splint to slide the lamp. For now seems good, we'll see if will be good in a year or two (I often remove and install the lamp). The handle holds the lamp well. I'm not convinced to gasket which protect micro USB port, it's bending when I connect USB cable. But maybe it will withstand some time. I think it's very good lamp when it costs under 20 $. Photos: low/high/middle from one side/appearance/appearance at close range
Неплохой фонарь , у меня в дополнение к основному. Цвет светодиода холодный, это не очень хорошо для меня, но в паре с тёплым белым источником получается самое то.
